Appl. No.:

10/357179

Inventors:

James D. Huffman - Plano TX, US

Assignee:

Texas Instruments Incorporated - Dallas TX

International Classification:

G02B026/08

US Classification:

359224, 353 99

Abstract:

A digital micromirror device with an optimized beam dimple formed over the via2 to provide process margin by increasing the clearance between the beam and the address electrode, thus reducing shorting between the two. This approach assures that when the beam tilts, it will land on its tips prior to making contact between the beam and address electrode, which are at different potentials. Beam dimple optimization is controlled by the characteristics of the via2 located on the lower metal-3 layer of the device.

Abstract:

A scalable persistent memory for a computing resource includes a scalable persistent memory region allocated in system memory of the computing resource. In case of system shutdowns, the contents of the scalable persistent memory region is transferred to a backup storage resource. Transfers to the backup storage resource occur in data blocks consisting of a plurality of data lines. A data block may be rejected by the backup storage resource if the data block is found to contain data errors. For any data block rejected by the backup storage resource during a data transfer, the rejected block is scanned in data line increments and scrubbed by replacing or overwriting any data line found to contain an error with error-free data. A scrubbed block is then stored in a known good region of system memory previously determined to be error-free. The previously rejected data block is then transferred from the known good region to the backup storage resource. Data recovery from the backup process is maximized through avoidance of entire data blocks being rejected.
